Winter’s temperature swings may create uncertain weather, but they also provide an opportunity for farmers to enhance their pastures and hay fields. Frost seeding, a method of broadcasting seed on frozen ground, takes advantage of the natural freeze-thaw cycle to improve seed-to-soil contact, increasing the chances of successful germination.
Why Frost Seeding Works
For seeds to germinate, they need good contact with the soil. Since frozen ground prevents traditional planting, frost seeding allows farmers to spread seeds earlier with fewer costs. As the soil thaws, it pulls the seeds deeper, promoting natural seed placement.
Best Time for Frost Seeding
Frost seeding works best from late February to early March, just before temperatures rise consistently. The repeated freeze-thaw cycle during this time helps ensure better seed integration into the soil.
Recommended Seeds and Rates
Legumes are ideal for frost seeding, with red clover, white clover, birdsfoot trefoil, and alfalfa being common choices. Recommended seeding rates include:
- Red clover & alfalfa: 6-8 lbs/acre
- White clover: 2-4 lbs/acre
- Birdsfoot trefoil: 4-6 lbs/acre
A few grass species like perennial ryegrass, tall fescue, and orchard grass can also be frost-seeded. Seeding rates should be:
- Thickening a damaged stand: 10-15 lbs/acre
- Establishing a new field: 20 lbs/acre
Upcoming Farm Programs
Several agriculture programs are available in February and March, including:
- Ohio Dairy Quality Conference (Feb. 11-12)
- NE Ohio Dairy Conference (Feb. 28)
- OSU Small Farm Conference (March 8)
- Farm Transition Workshop (March 11-13)
